Positioning the Electrodes
Lateral View, Precordial Electrode Placement (top)
Front View, Limb and Precordial Electrode Placement (bottom)
When the electrode sites have been identified and prepped, remove the clear electrode covering and apply an
electrode to each of the (10) sites. Secure each electrode by exerting slight pressure around the outer edge and inner
ring of the electrode.
To connect the leadwires, begin with connecting the LL leadwire (Red – labeled LL) to the LL electrode. Connect
the next leadwire on the cable (Fuchsia – labeled V6) to the V6 electrode. Continue connecting the snap connectors
to the electrodes as positioned on the main cable.
Note: QRS morphology may be slightly different from the standard 12-Lead ECG due to modification of limb
electrode placement.
